    I/O (Sterndrive) Conversion to Outboards

    If it's not grinding, it's drilling . . . I went through several cobalt bits . . . amazing what a sharp drill can do . . . It reminds be of way back, when I was a young engineer in an electronics manufacturing company. The VP said "the printed circuit board fabrication line was having...

    I/O (Sterndrive) Conversion to Outboards

    Speaking of bolts . . . I still have bad memories of 'galling' on some of the stainless steel fasteners when I did my extended swim platform on the Formula 330. It seems like the preferred solution to avoid galling is to use some anti-seize on the threads. Bolts/nuts are 316 stainless...

    I/O (Sterndrive) Conversion to Outboards

    Speaking of pins and spacers . . . I made some adjustments to the 'pins' in order to make the installation easier and repeatable. . . I ground the ends of the bolts to make them look/act more like pins. I also have them slightly loose to the have some play needed for the initial alignment...

    I/O (Sterndrive) Conversion to Outboards

    @flashback , here is a diagram that I used to show the need for spacers to some folks on another forum ( some people . . . :rolleyes: ). Essentially, the beveled sides, as built, ended up being a 'tad' too wide for the transom. As such, the extension bracket would find itself off-center...

    I/O (Sterndrive) Conversion to Outboards

    No there are (will be) spacers that are thicker than the nuts . . . The transoms of the boat & extension bracket do not come in contact. (the bevel sides interfere with the fit). Thus the hull & deck adhesive putty to fill the gap.

    I/O (Sterndrive) Conversion to Outboards

    Installation Update . . . I got the extension bracket aligned with the different (0.45") spacers. As such, I drilled the 'pilot' holes and put the 'installation guide pins' in at the 4 corners of the extension bracket. They will need a little bit of play in order to align with the matching...

    I/O (Sterndrive) Conversion to Outboards

    The center stringer support is done. I do plan on putting in a floor of some sort to make for a decent storage area. The new stringer will play a role in supporting a floor. I did another test fit and decided to go up a 'wee bit' on the spacers. (0.45" up from 0.35"). The thinner ones were...

    "set them in place" to keep the cold out. They will be gone once I don't need them.

    I/O (Sterndrive) Conversion to Outboards

    The sun is shining so I'm doing some more glassing. I did the crossbar pieces over the past couple of days, and today I glassed the center stringer . . . 4 layers wet-on-wet. . . With the sun out, temperatures in the boat are 80˚F, even though it is only 60˚F outside. To keep the coldness...

    Blessed

    I took it @ 70. . . a while back I did a calculation of taking it earlier or waiting. There was about a 8-9 year break even point. Thereafter it is a gravy train.

    I/O (Sterndrive) Conversion to Outboards

    I am glassing today . . . not quite warm enough, but I got a heater going and using 2.25% MEKP . . . seems to be working . . . but it is not quick. :ROFLMAO:

    You wouldn't have tooling resin in a production piece. :unsure: That (red) is the fiberglass (resin). Not sure what it is, but probably a VE resin. The VE resin I used on the extension bracket is more green in hue.

    Day 3 (or 4) of grinding . . . . . A few more areas to do, but it is getting close.

    I/O (Sterndrive) Conversion to Outboards

    I am out of 40 grit disks, which was fine for today, as I can only do so much grinding in a day. . . I'll be getting more 40 grit, because the underside of the swim deck needs some grinding . . . not the hole area, but where I want the contact points.

    I/O (Sterndrive) Conversion to Outboards

    I'll just do the best I can on the inside. The outside (where it really counts) is going well though . . . . . I bought 20 flap disks (40 grit), and there are not many left. I've got some 60, 80, and 120 grit as well, but 40 grit is for the grinding.

    I/O (Sterndrive) Conversion to Outboards

    The wire cup wheel was a bust . . . it just can't get into the groves to any extent. Since it is cold(er) and damp this AM, I started the grinding on the outside on the transom. Much better and goes fairly quick with the 'corded' angle grinder. :D . . The gelcoat on this boat is fairly thick...

    Since I'll be scarf joining and gelcoating, I chose to stay away from epoxy.

    I/O (Sterndrive) Conversion to Outboards

    I'll try that . . . The main stringer is nothing but corduroy . . . :cautious: I did go back (just now) and hit some of the low spots. This is what I'm trying deal with . . . Plenty thick on the outside, not so much on the inside. . . I did not want to grind too much more. There is some...
